ASUS Innovation and Quality

The ASUS product portfolio includes notebooks, Eee PCs, motherboards, graphics cards, wireless, and much more.

In 2008 alone, ASUS products won 3,056 distinguished awards thanks to the innovative user-centric technologies such as ASUS' exclusive EZ MFP, the easiest way to share an USB multifunction printer wirelessly with multiple users.

EZ Multifunction Printer (MFP) Sharing

Share your USB MFP with up to total of 12 users, wirelessly! With the EZ Multifunction Printer Sharing feature, up to 12 users can share an USB multifunction printer to print and scan wirelessly using the ASUS WL-520gU.

The WL-520gU utilizes an auto switching function that automatically switches users as needed and eliminates the trouble of disconnecting/reconnecting when users take turns printing. This saves you from purchasing a costly 24 hr. dedicated printing station PC or dedicated print server.

With a quick setup and easy USB connection for EZ MFP Sharing, the ASUS WL-520gU is the ideal wireless router for small office and home businesses.

EZ and Quick Setup with EZ UI (Easy User Interface)

    I want to preface this review with a warning, if you don't intend to use Tomato or DDWRT firmware on this device then DO NOT purchase it! That being said, I popped this out of the box and installed Tomato ND almost immediately. The general consensus on the stock firmware is that it is abysmal and not worth touching!

    So far I have three of these running, one at home and two at the office. All of them have been running flawlessly for months. I think my longest runtime is 80 days, but only due to power outages! The office ones are also running WDS, with the main one running a modified Tomato ND version with OpenVPN, which also works flawlessly.

    I was slightly concerned about ventilation on these boxes, as they are just plastic with two minor vents yet I haven't had any issues. One of the office WDS links is running in an unventilated computer cabinet and hasn't had so much as a hiccup. One thing to note on WDS though is that I was unable to get them to run unless I used WPA/AES, TKIP would not work at all. This isn't a big deal, but is counterintuitive during setup.

    Whether you choose to run Tomato ND or DDWRT is entirely up to you, but I don't think you will be disappointed with either one! Initial setup can be daunting for the technically challenged, but there are walk through guides out there. Definitely worth every penny, especially if you can get one with a rebate!

    UPDATE: Just wanted to update everyone. I thought my uptime record for one of these boxes was 80 days, but I just checked on one attached to a UPS and it came in at an incredible 230 days!!! To me that speaks volumes about these little boxes.

    This router router can do a lot more if you replace the original firmware with DD-WRT, Tomato or OpenWRT:

    VPN, OpenVPN, NAS, BitTorrent, radio output power control, Wireless Print server, etc. It is possible to use a USB hub to connect several devices including printers.

    Possibilities are endless.

    Just as so many people have said this before, make sure you grab the DD-WRT firmware or the tomato firmware with the teddy bear mod and you should be just fine. its an amazing product. I havn't had it go down once in the last month I have had it. It pairs nicely with my Linksys m100 cable modem for Comcast. I am pushing close to 20 Mbps constant. I was very concerned about how much power this USB port had on it and if I needed a powered USB splitter or not. Well I took the risk and I have a 4 port Belkin Mini Hub (F5U407) connected to it so I can connect my printer and my usb HDD to it and it works great! Tomato allows me to run a FTP and opendns all with my dyndns account always being updated without a computer which is very nice. I used duct tape and taped the hub to the top of the device and it looks good. I am getting a super fast connetion to the internet through my wireless although I havn't ran it through any tests its plenty fast for online gaming. Also I run a media center from my PC to laptop that connects via HDMI to my plasma and it works fantastic, not one hiccup during movies or music so far.
    The deivce doesn't seem to get hot at all. just a slight warm. all in all it looks good, works as it should, and just blows past my expectations.
    The only thing that would have been nice is 802.11n support but right now I am ok with it.

    I read all the reviews, and I've used DD-WRT in the past, so I thought this router would do more, for about the same price or less than I could get one locally.

    Reading the reviews, I knew the multi-function printer would be iffy, but I really wanted to try to get a network scanner working. Hey, it says it will do it right here in the Amazon description.

    Out of the box, I had my multi-function printer printing over the network in about 15 minutes. Three hours later, I gave up on scanning over the network. As someone pointed out, not all multi-functions are supported, and even if they are supported, not all functions are supported. So you may be able to print, but not scan. If you search a lot, there is a list of supported printers, and what functions will work. Scanning is not supported on quite a few printers.

    Also, I was in hurry and did not put DD-WRT on it. The stock firmware has DHCP issues. I put it behind a DSL modem in a double NAT setup because I needed to isolate a group of computers from the rest of the network. Internet worked on about half the PCs in the office. After a little hair pulling, I figured out that the router was not correctly passing the DNS IP addresses. To make sure it wasn't me, I defaulted the router a couple of times. Still, only about half the computers were working. The only way I could fix the issue was to manually put DNS IP addresses into the router for it to hand out on its DHCP server. All computers went right to work at this point. We have a mixture of OSes, too. Windows XP Pro/Home, Windows 7 Home, and Android/iPhones. It wasn't just one OS version that wouldn't work. Windows 7 wouldn't and Android wouldn't, but XP Home/Pro did, as well as the iPhone.
